TE Connectivity AMP Connectors 5221221-5 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 5221221-5 is an active BNC connector jack designed for 75-ohm coaxial applications. This female socket connector features panel mount installation with bulkhead front-side nut fastening and crimp termination for both center contact and shield. The connector supports RG-179, 179A, 179B, 187, and 187A cable groups with a maximum frequency rating of 2 GHz and operating temperature range of -65°C to 85°C. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when design requirements permit component flexibility within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity AMP Connectors 5221221-5 are identified based on strict equivalence of core electrical and mechanical parameters. The following parameters must match or exceed the main part specifications to qualify as a valid substitute:

• Connector Style: BNC (exact match required)
• Connector Type: Jack, Female Socket (exact match required)
• Impedance: 75 Ohms (exact match required)
• Contact Termination: Crimp (exact match required)
• Shield Termination: Crimp (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Mounting Feature: Bulkhead - Front Side Nut (exact match required)
• Fastening Type: Bayonet Lock (exact match required)
• Voltage Rating: 500 V minimum (equal or higher acceptable)
• Mating Cycles: 500 minimum (equal or higher acceptable)

The Amphenol RF 031-71016-RFX meets all mandatory electrical and mechanical parameters and qualifies as a direct substitute for the TE Connectivity part.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity AMP Connectors 5221221-5 and Amphenol RF 031-71016-RFX are active products with current manufacturing status. Both parts maintain RoHS compliance and REACH affected status with identical ECCN and HTSUS classifications.

The TE Connectivity 5221221-5 is suitable for applications requiring the specified 2 GHz maximum frequency with 0.15 dB insertion loss performance. The part is RoHS Compliant and carries unlimited moisture sensitivity level rating.

The Amphenol RF 031-71016-RFX provides equivalent electrical and mechanical performance with extended frequency capability to 4 GHz, supporting additional cable group options including Belden 9221 and M17/94-RG179. This part is ROHS3 Compliant and also carries unlimited moisture sensitivity level rating.

Selection between these parts depends on application frequency requirements and cable compatibility needs. Both parts satisfy the core 75-ohm BNC jack panel mount crimp termination specification with identical voltage and mating cycle ratings.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 031-71016-RFX be used as a direct replacement for the TE Connectivity 5221221-5?

A: Yes. Both connectors share identical BNC jack female socket configuration, 75-ohm impedance, crimp termination for center contact and shield, panel mount bulkhead installation, bayonet lock fastening, 500 V voltage rating, and 500 mating cycles. All core electrical and mechanical parameters match.

Q: What are the differences between these two parts?

A: The Amphenol RF part supports higher maximum frequency (4 GHz versus 2 GHz), has slightly higher insertion loss (0.2 dB versus 0.15 dB), uses different center contact material (Phosphor Bronze versus Beryllium Copper), different body material (Brass versus Zinc), and different dielectric material (POM Acetal versus Polyethylene). The Amphenol part also supports additional cable groups.

Q: Are both parts RoHS compliant?

A: Yes. The TE Connectivity 5221221-5 is RoHS Compliant. The Amphenol RF 031-71016-RFX is ROHS3 Compliant. Both meet RoHS requirements.

Q: What cable types are compatible with each connector?

A: The TE Connectivity 5221221-5 supports RG-179, 179A, 179B, 187, and 187A cable groups. The Amphenol RF 031-71016-RFX supports the same cable groups plus Belden 9221 and M17/94-RG179.

Q: What is the operating temperature range for these connectors?

A: The TE Connectivity 5221221-5 operates from -65°C to 85°C. Operating temperature data for the Amphenol RF part was not provided in the specification.

Q: How many mating cycles are rated for each connector?

A: Both connectors are rated for 500 mating cycles.

Q: What is the packaging configuration?

A: Both parts are supplied in bulk packaging. Each connector includes 7 pieces: 1 connector, 1 contact, 1 ferrule, 1 gasket, 1 lockwasher, 1 nut, and 1 sleeve (TE Connectivity) or 1 insulator (Amphenol RF).
